Hi Mac24, since about days my jeep starting after 3 minutes and +50 tries turn on the key .. I think it's the starter.. The battery is new.. I hear the fuse contact ! It's possible that problem come from solenoid ? Wire ? Starter ?
 
Thank You Dave

If I understand correctly, it takes many turns of the key before the starter turns, although you can hear it click each time?
 
The solenoid is integral to the starter and can't be replaced seperately, so if the problem lies with the solenoid or the starter a replacement starter is required.
 
It's also possible that you have a bad (high resistance) connection at either of the battery connections, the starter connection, or the engine ground.
That would be where I'd start my checks, and if that's the problem it'll be a lot cheaper than an exchange starter.

#16 of 20 98 Wrangler 4 Cyl. TPS Issue by bezzer344

Jun 03, 2009 (2:14 pm)

Hi,
 
So after giving my Jeep a tune-up, and a new water pump, i noticed that when driving it at a certain point in the throttle it would sputter and buck, if you if will, but would stop both sputtering and bucking if I either let off the throttle or gassed it a bit more. So it was then hooked up to a computer to see what the problem was and it turns out that the TPS was the problem. So I went to a local parts store(NAPA) and got a TPS, installed it, and when I started the jeep the rpms went went up to about 2100 rpms and idled there. Thinking/hoping that the problem might be because it was not an authentic mopar part, I went and got a TPS from a dealer and still it does the same thing: starts and goes up to 2100 rpms and idles...
 
Any ideas as to what the problem may be???
 
Thanks,
Dave

As this started after you did the 'tune up' it migh be worthwhile to go back and check over your work. Most likely cause is a disconnected or split vacuum hose.
You can also do a basic rest of the PCM by disconnecting the battery for ten minutes.
 
It's also possible you have a problem with the IAC (Idle Air Control) motor, or the inlet passage to it. You may even find a cleaning of the throttle body and the IAC passage will do the trick.

I see you mention a PCM on this post. I just had my 07 Sahara in the shop and that is what they said they replaced, my OBD light was on that is why I took it in. When I picked up my car the techs and advisor were all gone, Can you tell me what excatly a PCM is and what it does in plain english so a girl can understand it?

PCM= Powertrain Control Module- it's the computer that operates the engine and-if fitted-the automatic transmission.

And I believe it is warrantied up to about 80,000 miles since it is considered part of the emissions systems.
